Hochschild上同调与量子Drinfeld Hecke代数

Hochschild cohomology and quantum Drinfeld Hecke algebras

Deepak Naidu, Sarah Witherspoon

摘要:

量子Drinfeld-Hecke代数是Drinfeld-Hecke代数的推广,其中多项式环被量子多项式环取代.我们确定这些代数作为变形的斜群代数,给出一个明确的连接到Hochschild上同调。我们计算的相关部分Hochschild上同调的行动,许多反射群,我们利用计算从我们的论文与Shroff对角行动。结合我们的工作与最近的结果Levandovskyy和Shepler,我们产生的量子Drinfeld Hecke代数的例子。这些代数推广了Bazlov和Berenstein的辫子Cherednik代数。

英文摘要:

Quantum Drinfeld Hecke algebras are generalizations of Drinfeld Hecke algebras in which polynomial rings are replaced by quantum polynomial rings. We identify these algebras as deformations of skew group algebras, giving an explicit connection to Hochschild cohomology. We compute the relevant part of Hochschild cohomology for actions of many reflection groups and we exploit computations from our paper with Shroff for diagonal actions. By combining our work with recent results of Levandovskyy and Shepler, we produce examples of quantum Drinfeld Hecke algebras. These algebras generalize the braided Cherednik algebras of Bazlov and Berenstein.
